The textures of the cold-rolled and annealed Ni47Ti44Nb9 sheets have been studied using the orientation distribution function(ODF) method. The results indicated that the cold-rolled sheet showed a dominant{100}p face texture, and its recrystallization textures could be described with{001} <100>p. Moreover, when the cold-rolled sheet was annealed at 700 or 850℃, there occurred abnormal coarsening, thus forming a new kind of annealing texture{001} <110>p.
